MAP65

This webpage will discuss setting up a dual-receiver system using MAP65 as software for
providing Adaptive Polarity Reception of JT-65 eme signals.
Specifically, the EME receiver is an Elecraft K3 with KRX3 sub-receiver option, fed by a dual-channel
transverter converting 144-MHz to 28-MHz. The first IF (8.215-MHz) is tapped from both the Main
and sub receivers of the K3 to drive two Telepost, Inc. LP-Pan SDR. The LP-Pan convert the IF
into two quadrature baseband audio outputs which are input to a M-Audio Delta-44 soundcard which
produces two I/Q data streams for direct use by MAP65 version2.
